Guest Post by Werner Brozek, Edited by Just The Facts: First of all, I wish to draw your attention to the graph of UAH6.0beta5 with a mean of 12. (Yes, WoodForTrees.org has finally been updated, at least for UAH6.0beta5 and Hadcrut4.4 and WTI!) On the graph, it can be seen that the mean 2016 values…

Satellite data shows globe will stay below 1.5°C target at the current rate of warming, resulting in 1.1°C December 18: University of Alabama, Huntsville The average temperature of Earth’s atmosphere has warmed just over four tenths of a degree Celsius (almost three fourths of a degree Fahrenheit) during the past 37 years, with the greatest…

Guest Post by Bob Tisdale As you are well aware, there is a very basic difference between the updates to the NOAA and UAH global temperature datasets: the NOAA update increased the warming rate of their product during the slowdown in global surface warming, while the UAH update decreased the warming rate of their lower…

Guest Post by Willis Eschenbach The satellite-based atmospheric temperature dataset is one of the better datasets in climate science. Drs. Roy Spencer and John Christy have long been scientific heroes of mine because of the quality of their work in the creation, analysis, corrections, and curation of the dataset. It is kept at the University…

Guest Post by Werner Brozek, Edited by Just The Facts: Some of you may have wondered why the title and the above plot are comparing different data sets. The reasons are that GISS and HadCRUT4.3 are very similar. As well, UAH6.0 is now very similar to RSS. However WFT does not have the latest UAH…

Guest Post by Bob Tisdale It’s been 25 years since Spencer and Christy of the University of Alabama at Huntsvillle published their 1990 paper Precise Monitoring of Global Temperature Trends from Satellites. The abstract reads (my boldface): Passive microwave radiometry from satellites provides more precise atmospheric temperature information than that obtained from the relatively sparse…

…And what we might expect from the GISS, NCDC and UKMO products. Guest Post by Bob Tisdale Alarmists from around the globe are awaiting the global temperature product update from GISS, which should be released sometime around the 15th of this month. As a separate listing, see the data page here, GISS provides the annual-average…

UAH Global Temperature Update for February 2014: +0.17 deg. C (Note, my original headline number was unintentionally misleading, using a percentage to illustrate the drop rather that the absolute number. While the calculation was correct, it gave an impression of overall magnitude across the entire scale rather than the month to month change. It has…

Note that the original October report on WUWT from a press release issued accidentally by UAH is superseded by this report. – Anthony UAH v5.6 Global Temperature Update for October, 2013: +0.29 deg.

UAH V5.5 Global Temp. Update for Sept. 2012: +0.34 deg. C By Dr. Roy Spencer As discussed in my post from yesterday, the spurious warming in Aqua AMSU channel 5 has resulted in the need for revisions to the UAH global lower tropospheric temperature (LT) product.
